ALEXANDERI JV. BEGG, OF NEW YORK, N. Y.

T0 (ZZZ whom it may concern 'Be it known that I, ALEXANDER L. WV. BEGG, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have inventedcertain new and useful Improvements in Me chanical Flight, of which the following is a specification. e

Theobject of the present invention is to provide a new mechanical movement in the nature of a rotating shaftthat carries one or more shafts rotatably mounted thereon to extend transversely, and provided with vanes that are caused tofeather, whereby the fluid medium in which the device operates, either air or water, will react on the device and effect its propulsion, in the desired direction, either upward or forward. a

'It is an object of the invention to provide means for propulsion that will admit of movement in the preferred direction, be it either horizontal or vertical. Anotherpurpose is the use of planes which may be used as a sustaining means or not at will. Another purpose being if so used as a sustaining means, the power, through such use, will be propulsive in proportionto the degree the planes-are brought into positionto be sustaining. V

In the accompanying drawing illustrating an embodiment of my invention, Figure 1 is a plan View of one form. Fig. 2 is; an end elevation of the same. 3 is a side elevation of the device. Fig. 4 is a vertical section enlarged showing the mounting of one transverse shaft on the main shaft. Fig. 5 indicates a modification; and Fig. 6 is a diagram indicating the feathering of one of the transverse shafts with its blades in different positions.

The device in the preferred form illustrated comprises a frame on which one or a pair of driving shafts are mounted, preferably driven by a motor on the frame. Each driving shaft carries a series of shafts rotatably mounted thereon and extending transversely; and which shafts are caused to rotate on rotation of the driving shaft and preferably at half the speed of the driving shaft and which transverse shafts are provided with blades arranged in transverse planes on the opposite ends of each shaft respectively. 7

As shown, I provide a framework on which a pair of shafts 8 and 9 are rotatably MECHANICAL FLIGHT.

mounted in parallelism at the upper part. On the shaft 8 is mounted a series of trans- .verse shafts 10 that are free to rotate, and

which are provided with blades 11 and 12 on opposite sides of the main shaft 8, the 'bladeson each shaft being in planes that are at right angles, as shown in Fig. 1. Suitable means are provided whereby the rotation of the shaftS will cause all of the transverse shafts 10 to revolve inunison with each other and at half the speed of the shaft 8. That is, for each revolution of the shaft 8, the transverse shafts 10 make a half revolution, as they are bodily carried around by the main shaft. The blades on the shafts are placed in the same relative position, so that when the blades on one side are all parallel with the shaft 8, the blades on the opposite side of the shaft 8 lie in planes perpendicular to the shaft 8,, as shown in Fig. 1. .To efi'ect this rotation of the transverse shafts, I show a form of planetary gearing, each shaft 10 having a miter gear 13 fast thereon, that engages a miter gear 14 that surrounds the shaft 8 which is held stationaryby suitable means, such as a strut 15 of the framework. Since the gear 1 1 is half the size of the gear 13 when the shaft 8 is rotated all of the transverse shafts will revolve at half the speed of the driving shaft.

The frame 16 as shown is provided with a motor 20 driving a shaft 21, and the 1at-- ter by means ofbelts 22 and 23 drives the shafts 8 and 9 in opposite directions.

By this arrangement it will be understood that when the blades 11 are moving downwardly as indicated in Fig. 2, the blades 19 on the opposite side will also be moving downward; while the blades 18 and 11 of the two sets will move upward at this time. These several blades are so arranged that the outer sets of blades would have their blades extending in the horizontal plane, whereby the fluid medium will be forced downward, that by reaction would tend to elevate the blades and the frame by which they are carried. Since the blades moving upward at the middle portion of the frame are substantially vertical they will pass freely through the fluid medium.

. A plane 40 is provided arranged stationary on the frame between the revolving blades as shown. Guiding planes 41 are provided to swing on a shaft 42 whereby to control the movement of the craft. Suitable guiding planes 43 may also be provided to assist in controlling the direction of movement.

It will be readily understood that not only is this combination mechanism applicable to an air-and-land or air craft as illustrated in the foregoing preferred form, but also to. land vehicles, for propelling and partially sustaining them on occasion.

In operation the vanes 11, 12, 18 and 19 are normally the sustaining and propelling means, and consequently the progress is relatively slow because of the dependence of the vehicle on thevanes for both such purposes. When, however. it is desired to increase the speed of the vehicle, the weight of the vehicle, by tilting the vehicle laterally is thrown upon the plane 40 that is brought to a substantially horizontal position by such tilting, which plane then sustains the weight of the vehicle; and in proportion to the degree to which it is so sustained, the force of the vanes is devoted to propulsion more exclusively with resulting greater speed. 7

Having thus described my invention, what I claim is i 1. The combination ofa frame, a pair of driving shafts arranged parallel on opposite sides of the frame, means for driving the shafts in unison, a series of shafts carried bythe driving shaft and extending transversely thereto, blades on the transverse shafts, gearing for causing the transverse shafts to rotate as carried around by the driving shafts uniformly at half the speed of the driving shaft, and a vertical fixed plane on the frame intermediate of said shafts.

'2. The. combination of a frame, a pair of driving shafts arranged parallel on opposite sides of the frame, means for driving the shafts in unison, a series of shafts carried verselythereto, blades on the transverse shafts, gearlng for causing the transverse shafts to rotate as carried around by the driving shafts uniformly at half the speed of the driving shaft, and a vertical fixed plane on the frame intermediate of said shafts, and extended downwardly therefrom.

3. The combination of a frame, a pair of driving shafts arranged parallel on opposite sides of the frame, means for driving the shafts in unison, a series of shafts carried by'the driving shaft and extending transversely thereto, blades on the transverse shafts, gearing for causing the transverse shafts to rotate as carried around'by the driving shafts uniformly at half thespeed of the driving shafts, and a vertical fixed plane on the frame intermediate" of said shafts, and extended downwardly therefrom and deflecting planes below the said plane in'the same plane therewith normally, and means for swinging the deflectinglanes.

4. In an improvement in mechanical flight, in combination, revolving vanes that simultaneously sustain and 'PIOPEl flIId a plane adjacent'to such vanes that is normally vertical and inoperative, but which plane when the craft istilted to bring this plane to'a substantially horizontal position operates to sustain the craft.

5. In an improvement in mechanical flight, in combination, propelling vanes which normally move the entire craft, and a normally inoperative vertical plane adja cent thereto "which on Itilting the eraftto bring such plane to a substantially horizonal position is caused to sustain the weight of the craft and thereby enable the vanes to increase the speed. l i
